Topological Freeze-out by Semi-Annihilation

Posted by dbos Tokyo

Kavli Affiliate: Hitoshi Murayama | First 5 Authors: Joe Davighi, Serah Moldovsky, Hitoshi Murayama, Christiane Scherb, Nudzeim Selimovic | Summary: We point out that a QCD-like dark sector can be coupled to the Standard Model by gauging the topological Skyrme current, which measures the dark baryon number in the infrared, to give a technically natural […]

Structured Labeling Enables Faster Vision-Language Models for End-to-End Autonomous Driving

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Hao Jiang, Chuan Hu, Yukang Shi, Yuan He, Ke Wang | Summary: Vision-Language Models (VLMs) offer a promising approach to end-to-end autonomous driving due to their human-like reasoning capabilities. However, troublesome gaps remains between current VLMs and real-world autonomous driving applications. One major limitation is that existing […]
